What are the differences between SLA and FDM 3D printing?

SLA 3D Printing:

● Method: Utilizes a UV laser to cure liquid photopolymer resin layer by layer.

● Surface Finish: Produces parts with a very smooth finish and highly detailed features.

● Speed: Can print quicker compared to FDM, especially for complex designs.

● Materials: Uses photopolymer resins, which can be more expensive.

● Strength: Parts tend to be less durable than those made with FDM.

● Post-Processing: Requires cleaning in a solvent bath and post-curing.

FDM 3D Printing:

● Method: Build parts by extruding melted thermoplastic filament layer by layer.

● Surface Finish: Generally has a rougher finish and visible layer lines.

● Speed: Can be faster for simpler designs; speed varies based on quality and infill.

● Materials: Offers a wide range of thermoplastic materials, often at a lower cost.

● Strength: Produces stronger parts due to the mechanical properties of thermoplastics.

● Post-Processing: May require minimal post-processing like sanding for smoother surfaces.

In summary, SLA is preferred for projects requiring high detail and a smooth finish, while FDM is chosen for its material versatility, strength, and cost-effectiveness.
